As with any HVAC project, careful installation is the key to a successful outcome. Time taken during the installation process will be rewarded with fewer call-backs.

The steps required to install the 44-800 thermostat are as follows:

1. Read and understand this Installation Manual and Thermostat User Manual.

2. Mount and wire the subbase

3. Install the batteries

4. Set the 4 system switches to match the equipment application.

5. Wire optional remote temperature sensor(s).

6. Power the thermostat.

7. Set the Advanced Installer settings.

8. Test the thermostat.

GETTING STARTED

7

DISASSEMBLYThere are two release slots located on the bottom of the thermostat. Gently push the flat blade of a small screwdriver into one slot at a time and pry upward until the catch disengages. Carefully swing the thermostat upward and away from the subbase. (Figure 1)

THERMOSTAT LOCATIONThe 44-800 should be installed in a location that represents the ambient space temperature. Do not install the thermostat in an area where drafts are present, near the floor, behind doors or on an external wall. Avoid placing the thermostat in areas where the air movement is limited, affected by direct sunlight or other areas not typical of the temperature in the space.

MOUNTING THE SUBBASEWhen mounting the 44-800 subbase, be aware that drafts may travel down wall cavities and enter the back of the thermostat through the control wire hole in

the wall. It is important to seal the hole to prevent any drafts that might affect the internal temperature sensor. Pull the control wires through the large opening in the thermostat subbase. Next, level and mount the subbase on the wall using the supplied anchors and screws. (Figure 2)

Do not over tighten the mounting screws as the subbase may warp causing the improper seating of the thermostat connecting pins to the terminal blocks.

Use a properly sized screwdriver and back each screw terminal out (counter clockwise) before landing each wire to its dedicated terminal. Do not over tighten the terminal screws.Check to ensure that all wires are landed correctly and dressed properly to prevent any shorts. Refer to Typical System Wiring Diagrams in this manual for proper wiring. FIGURE 2

The 44-800 comes with two AAA batteries. Insert the batteries as illustrated for primary or backup power. Even if the thermostat is hardwired, battery backup is essential to maintain the real-time clock in the event of a power failure. All other memory is non-volatile in the event of battery or primary power loss. (Figure 3)

REMOTE SENSOR INSTALLATION

REMOTE SENSORSThere are two type of remote sensors. The RS-1 is a single sensor that can be used indoors or outdoors. The RS-2 contains two sensors. A combination of both sensors can be used for indoor temperature averaging with or without the onboard sensor. Use separate 18-2 shielded cable when wiring sensors.

INDOOR SENSOR WIRINGWhen the RS-1 is used as an indoor sensor, the 44-800 can be configured to allow only the remote sensor to control the temperature or a combination of remote and onboard sensors can be used for temperature averaging. Refer to 16:TT in the installer setup menu to select the proper remote sensor option. Indoor sensor wires to terminals S1 and SC. (FIGURE 5)

RS-1SENSOR

FIGURE 547

NoteIf using outside air or remote room temperature sensor(s) battery life will be drastically reduced.

If using remote sensors it is highly recommended to power the 44-800 from 24V


Locate the sensor in the same manner as the thermostat. Mount the sensor 300mm away

from any outside wall. Do not install the sensor behind doors, in corners or other dead air

spaces. Keep the sensor away from direct air flow, supply registers or near sources of heat

such as lamps and appliances. The maximum wire length from the sensor to the

thermostat is 30meters. Use a separate 18-2 shielded cable for sensor wiring. Prior to

wiring the sensor to the thermostat, use an ohm-meter or multimeter to measure the

resistance of the sensor. Measure at the end of the wires that will connect to the

thermostat. Confirm the resistance value (within 5%) to the temperature where the sensor

is mounted. Use a quality digital electronic thermometer to read the temperature at the

sensor. Remove the sensor cover and place the thermometer probe next to the remote

sensor to verify an accurate reading. Disconnect power to the thermostat when wiring the

sensor to the proper sensor terminals. Strip only as much insulation off of the wires as

necessary to provide a good contact with the terminals. The sensor is not polarity specific

so either sensor lead may be connected to either designated terminal on the thermostat.

48

USING MULTIPLE SENSORS FOR TEMPERATURE AVERAGING

Multiple indoor remote sensors can be wired in series/parallel for temperature averaging. The total value of the sensors must equal 10kÙ @ 25° C. The onboard sensor is not part of the equation even if it is configured as part of the averaging circuit. Figure 6 illustrates two RS-2 sensors used for averaging.

TESTING

The 44-800 incorporates a short-cycle timer which can be disabled during testing by setting slide switch 3 to the ON position. Once testing is completed, the timer needs to be re-initiated by setting the switch to OFF.

TESTING FAN OPERATIONTouch MODE until the word OFF is displayed. Touch FAN until the words Always On appear. After a brief moment, the internal fan relay ‘G’ will energize and the system fan should operate. Touch FAN again until the word Automatic appears. After a brief moment, the internal fan relay will de-energize and the system fan will shut off.

TESTING CONVENTIONAL HEATING AND COOLING OPERATIONTouch MODE until the word Heat appears. Touch the UP arrow and raise the set point a few degrees above the space temperature. After a brief moment, the internal heating relay ‘W’ will energize and the heating system should operate. The word Heat will flash continuously. If the thermostat has been configured for two stage heating, raise the set point a few degrees and the second stage heating relay ‘A’ will energize. Heat will flash twice, pause and repeat the sequence to indicate second stage has been energized.

52

TESTING

Touch MODE until Cool appears. Touch the DOWN arrow and lower the setpoint a few degrees below the space temperature. After a brief moment, the internal fan ‘G’ and cooling ‘Y’ relay will energize. The word Cool will flash. If the thermostat has been configured for two stage cooling, lower the set point a few degrees and the second stage cooling relay ‘A’ will energize. Cool will flash twice, pause and repeat the sequence to indicate second stage has been energized.

TESTING CONVENTIONAL HEAT PUMP OPERATION

When the 44-800 is configured for conventional heat pump operation, testing is the same as a heating and cooling system with the exception that the fan “G’ relay is always energized with compressor, auxiliary and emergency heat calls.

TESTING FOSSIL FUEL OPERATIONThis is NOT typically used in Australia.When the 44-800 is configured for fossil fuel operation, testing is the same as a

53

TESTING

conventional heat pump system with the exception that the heat pump is never allowed to run when the fossil fuel furnace is energized. Whenever the thermostat calls for second stage (auxiliary) heat, the compressor ‘Y’ relay is de-energized along with the fan ‘G’ relay and the ‘A’ relay energizes the fossil fuel furnace. With the installation of an outdoor sensor, both high and/or low balance point control can be used to prioritize heat pump or fossil fuel operation based on a selected outdoor temperature.

TESTING LOW BALANCE POINT (Heat Pump or Fossil Fuel)When an outdoor sensor is used with the 44-800, Installer Option 18:LB allows you to select a low balance point temperature. When the outdoor temperature falls below the low balance point setting, a call for heat from the thermostat automatically energizes the auxiliary heat ‘A’ relay. To test the low balance point setting, set 18:LB above the displayed outdoor temperature and force a call for heating. The ‘A’ relay will energize the compressor ‘Y’ relay will be bypassed. Set 18:LB below the displayed outdoor temperature and force a call for heating. The compressor ‘Y’ relay will energize and the ‘A’ relay will not energize as long as the thermostat does not call for second stage. After testing, reset the low balance point temperature to a normal operating range.

54

TESTING

TESTING HIGH BALANCE POINT (Heat Pump or Fossil Fuel)

High balance point is designed to prevent the auxiliary heat ‘A’ relay from energizing when the outdoor temperature is above the balance point setting. To test the high balance point setting, set 19:HB below the displayed outdoor temperature and force a call for second stage heating. The ‘A’ relay will not energize and only the compressor ‘Y’ and fan ‘G’ relays will be active. If the thermostat is placed in the E.heat mode, the high balance point is ignored and the ‘A’ relay will energized on a call for heat. After testing, reset the high balance point temperature to a normal operating range.

Adaptive Recovery is only available in programmable mode (Installer Menu 12:RC = ON). The Adaptive Recovery function of the 44-800 permits the user to program a time that a desired set temperature is required. The thermostat then calculates the most energy efficient time to bring on the equipment to reach the set point at the designated time. This calculation involves a complex control algorithm that compares the space temperature deviation from set point and rate of recovery history.
